Event-based Aspect-Oriented Programming (EAOP) for Java. EAOP 1.0 realizes the EAOP model through the following characteristics:
* Expressive crosscuts: execution points can be represented by events and crosscuts can be expressed which denote arbitrary relations between events.
* Explicit aspect composition: Aspects may be combined using a (extensible) set of aspect composition operators.
* Aspects of aspects: Aspects may be applied to other aspects.
* Dynamic aspect management: Aspects may be instantiated, composed and destroyed at runtime.

The tool provides a testbed for the experimentation of aspect languages. As such, it does not provide specialized languages for pointcuts and advice (such as AspectJ) but offers a framework for the definition of arbitrary aspects.
